Dental Crowns

Crown Aesthetics

If your smile is in need of a makeover, crowns can provide predictable results. Crowns can give an unattractive tooth back its beautiful shape and color. For smaller or worn down teeth, a crown can restore the natural size of the old tooth. A crown can replace either part of or the tooth's entire crown. For procedures requiring only the areas visible from the outside, a veneer may be an alternative option.

Full Porcelain Crowns

These are very aesthetic, bonded crowns. They are mostly used for front teeth because they are the most natural looking type of crown and are often used in "cosmetic" dentistry. There are many types, but they all have a common feature - no metal. They can occasionally break, but dental technology has advanced far enough to make them quite strong.

The Crown Procedure

A crown is sometimes termed a "cap" or "jacket." A crown will restore a large filling or a cracked tooth to its original size, shape and tooth color. A crown may be recommended after root canal therapy has been completed, as the tooth tends to become brittle and is more likely to fracture. A crown can strengthen and protect the remaining tooth structure and improves the appearance of your teeth. With the advances in technology we now have the ability to make ceramic crowns with no metal.

To place a crown, we must reduce 1-2 mm of the tooth to make room for it. We will then use a piece of thread or cord or use a laser to push the gum down around the tooth, to take an impression of the tooth. The impressions are sent to the lab where the crown is made. During that time, you will have a temporary crown. These crowns are usually made of plastic and are made in your dentist's office on the day of your visit. They are not meant to last. If a temporary crown is left in the mouth, the cement eventually washes out, and the tooth can decay.

At a second visit, your dentist will remove the temporary crown and test the permanent one. Sometimes crowns need additional polishing, or glaze or some other adjustment before they are placed. Once the crown is ready, it's cemented to your tooth.

Crown Lengthening

Crown lengthening is a surgical procedure that recontours the gum tissue and often the underlying bone of a tooth. Crown lengthening is often needed for a tooth to be fitted with a crown. It provides necessary space between the supporting bone and crown, which prevents the new crown from damaging bone and gum tissue.
